[PATCH v19 0/7] ring-buffer: Making persistent ring buffers robust

[Masami Hiramatsu (Google)]

Hi,

Here is the 19th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177701351903.2223789.17087009302463188638.stgit@mhiramat.tok.corp.google.com/

This version rebased on v7.1-rc1 and cleanup code.

[2/7] Limit max number of loops to nr_pages in __rb_get_reader_page()
      and update comment.
[3/7] Cleanup rb_validate_buffer() so that it is more readable,
      and add a comment about the timestamp validation.
[6/7] Add a kerneldoc about rb_validate_buffer().

Thank you,
